- Most of fetal growth last 1/3 of gestation
- Body weight increases 75 lb
- Feed about 4 to 4.5 lb/d of corn soybean meal diet containing 1,450
kcal ME/lb
- ME = 5,800 to 6,500 kcal/d
- CP = 14% or 250 g/d
- Ca = 0.8% (14.5 g) P = 0.65% (11.5 g)
Lactation
- Requirements increase 3 to 4 x
- Produce about 2 lb milk/pig/d
- Full-feed gestation diet - 12 to 16 lb/d
- ME = 17,000 kcal/d
- CP = 16 to 18%
- Ca = 0.8%, P = 0.65%
Weanling Pigs
- Prestarter for about 1 wk, 1.6% Lys, 10 lb
- Dried whey (25-35%), dried plasma protein
- Phase 1 starter for 1 wk, 1.4% Lys, 15 lb
- Dried whey (25-35%), dried plasma protein
- Phase 2 starter for 2 wk, 1.2% Lys, 25 lb
- Dried whey (10-20%), dried blood meal/cells
